I0ML0

This program computes the difference of the modified Bessel
function of the first kind of order 0 and the modified Struve
function of order 0.

Description:

The I0ML0 function is defined as:

I0(x) -
L0(x)

with I0 and L0 denoting
the modified Bessel function of the first kind of order 0 and
the modified Struve function of order 0, respectively.

Dataplot computes this function using ACM Algorithm 757 (see
Reference: below). The function is computed using Chebyshev
expansions, the coefficients of which are given to 20 decimal
places.

Syntax:

LET <y> = I0ML0(<x>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a non-negative number, variable or
parameter;
<y> is a variable or a parameter (depending on what
<x> is) where the computed I0ML0 function
values are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
